A Pasadena police officer was injured as he tried to arrest a man who had threatened to hurt customers at a local restaurant Sunday.

The officer had responded to a call about a man threatening to stab customers with a pencil at Plate 38, a restaurant in the 2300 block of East Colorado Blvd. When he arrived at the restaurant, the officer saw a man sitting in the patio area, according to Pasadena police Lt. Pete Hettema.

Asked if he had a weapon, the man said he had a knife in his waistband and showed it to the officer. As standard procedure, the officer asked the man to stand up and turn around, but the suspect ran.

The officer pursued the man and caught up with him, but in the process suffered minor injuries.

Other officers who arrived on scene used a Taser on the suspect when he refused to obey commands and attempted to reach for his knife.

Hettema said firefighters treated the injured officer on site.

Police identified the suspect as Jonathan Crutchfield, 30, of La Puente. He was arrested on suspicion of resisting an officer, a probation violation and possession of narcotics, and booked at the Sheriff’s Inmate Reception Center in Los Angeles, police said.
